Painting only
For a painting-only scope — corridors, lobbies, stairwells, suites — the price is by wall and ceiling area with trim by the linear foot, the same way a house is priced, with an occupied-building tier for common areas. Materials are Sherwin-Williams: SuperPaint Interior on walls, ProClassic acrylic-alkyd on doors and frames, flat ceiling white on ceilings, and Pro Industrial enamels where a scrubbable or chemical-resistant finish is specified.

Related questions
- What does an office build-out cost per square foot?
- The February 2026 budget for a 3,876-square-foot spec suite and corridor at a Class A office building in Sunrise came to $321,407 including a permit allowance — about $83 per square foot. Finishes (paint, carpet tile, LVT and base) were $31,350 of that; HVAC and electrical were the two largest divisions at $54,550 and $72,076. Every division is on the proposal so the tenant can see where the money is.
- Can you paint corridors and common areas while the building is occupied?
- Yes. Occupied common-area work is priced as its own tier — corridors and a high lobby cost more per square foot than an empty suite because of protection, working around residents and hand cut-in where a sprayer cannot be used. Working hours and elevator use are agreed with management before the schedule is set.
- Do you handle permits and the other trades?
- Yes, under Florida Certified Building Contractor license CBC1264505. Framing, drywall, doors and glass, millwork, HVAC, electrical, plumbing, fire alarm devices and low-voltage pathways are in the proposal, with licensed subcontractors under Atrium's supervision. Permit fees are an allowance billed at cost.
- What is excluded from a tenant-improvement proposal?
- Hazardous materials testing and abatement, structural modifications unless shown on the drawings, major base-building reroutes, fire sprinkler relocations unless engineered, fire alarm panel upgrades, low-voltage cabling and IT hardware, and furniture and appliances. Allowance-based items — the door schedule, ceiling grid versus tile-only, carpet versus LVT by room — are stated and reconciled to actual cost.
